Distance measuring camera

A distance measuring camera, comprising:

• a first optical system for collecting light from a subject to form a first subject image;
• a second optical system for collecting the light from the subject to form a second subject image, the second optical system arranged so as to be shifted from the first optical system in a direction perpendicular to an optical axis direction of the first optical system;
• an imaging part for imaging the first subject image formed by the first optical system and the second subject image formed by the second optical system;
• and
• a distance calculating part for calculating a first candidate for the distance to the subject based on an image magnification ratio between a magnification of the first subject image imaged by the imaging part and a magnification of the second subject image imaged by the imaging part and a second candidate for the distance to the subject based on a parallel disparity between the first subject image and the second subject image,
• wherein the distance calculating part selects either one of the first candidate and the second candidate as the distance to the subject according to a predetermined condition.
